Application filed october 15,'1919. serial No. 330,742.

To all 107mm t may concern:

Beit knownthat LCARL D. BROWN, a citizen of the United States, and a resident of Hopedale, in the county of Vorcester and State of Massachusetts, have invented an Improvement in Filling-Replenishing Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

The invention to be hereinafter described relates to filling replenishing looms, and more particularly to the means for insuring control of the filling leading from the iilling carrier or bobbin which is to be ejected.

It is the usual practice in filling replenishing looms to part the filling between the cloth selvage and shuttle when the filling is to be replenished,"but since the parting `meanshas usually acted upon the filling near the entrance lto the shuttle-box, a long trailing end of iilling thread has extended from theilling carrier or bobbin'in the shuttle, through the side delivery eye of the shuttle, and longitudinally' of the shuttle box. This piece of filling thread, which may be termed the trailing end is intendedt'o be withdrawn from between the v,shuttle andthe "shuttle-box and backward throughthe Vside delivery'eye,"wlien the depleted lilling carrier orbobbin is ejected from the shuttle. VShould the trailing end fail to be withdrawn, Vas above stated, it is liable to be carried into 'the shed on a subsequent pick and producea defect in the cloth, and various means have been provided -for making more sure the withdrawal of the trailing end; The shuttlebox is Vusually wider atv'the Yentrance end lthan at its closed outer end, and the consequence is thatthe trailing end, after'` being parted 1 between the shuttle `and the Vcloth selvage,' is liable to drop downwardly betweenthe shuttle'and adjacent wallof'the shuttlebox and be 'pinched between them, with the result that. as the filling carrieror bobbin is ejected, the trailing end `will be broken, leaving a small piece `pinched between the shuttle "and". shuttle-box, Ywhich may eventually find its way into the shed and injure the quality of the .cloth woven.

One of the objects ofthe present invention, therefore, consists in means for preventing the trailing end from being pinched between -the shuttle and the wall of the shuttle-box and tohold it'elevated yetwith permissive movement longitudinally of the shuttle and through the shuttle eye as the filling carrier or bobbin is ejected.

Other objects of the invention, in addition to the above, will hereinafter be referred to `in connection with the accompanying drawings which show one good practical form of the invention.

Fig., 4 is a detail showing one form of` means for holding the bristles or tufts in fixed position, but with capacity for adjustment. Y

The general constructionv and mode of operation of the loomin which this invention may be advantageously employed, is well understood by those skilled in the art and needs no detailed illustration or description. 'The loom frame and the filling supplying mechanism, together with the usual hopper, are not here illustrated since they have no special connection with the invention itself.

The lay l may be of usual construction and provided with the shuttle-box 2 at the' fillinfT re Jlenishino' side of the loom in e l e 1 which the picker 3 may operate to pick the shuttle 4. The shuttle box 2, as usual, is provided with 'an opening at its lower surface through which may be ejected the filling carrier 5 contained in the shuttle 4.

In the present instance of the invention,

the front wall Grof the shuttle box is, ad-

justably secured to the lay by the bolts 7 which pass through the'slotted lugs 8 con- Vnecting Vthe front wall 6 of the shuttle box with the lay. At its entrance end the front wall of the shuttle box is flared outwardly somewhat, as indicated at 9, to thereby provide 'a widened or enlarged entrance end to permit the shuttle to surely enter the shuttle box even though it may be deviated some- -what from its direct path during the picking operation.

The inner surface of the front wall 6 of the shuttle-box is provided with a frictional substance, such as leatherv or similar material 10, to furnish frictional resistance to the Ashuttle as it moves to the outerend ofy the filling carrier V5 in theshuttle passes, and,v

'extending longitudinally'of the shuttle from the side delivery eye, isv a groovejl). in which it is desirable that the filling thread 13, Fig.

3,:-may lfie when the shuttle is inthe re-V plenishing boXf. Obviously, if'the filling thread 13 which extends from the side ldelivery eyc to the entrance of the shuttle box or the point where the filling end has been partedbetween the cloth ,selvage and shuttle,

is maintained in the groove 12, it will not be pinched between the innen surface of the front wall of the shuttle-boxY and the outer surface ofthe side wall ofthe shuttle,

Vand may readily be withdrawn backwardly through the shuttle delivery `eye 'when Yreplenishment of filling is effected.

- .-'VVhen 'thei filling., is parted between the cloth Ase'lvage andthe shuttle, however, the

'terminal portion of the trailingend is liable to .drop Vdowmvardly lbetween the shuttle and the adjacent front wall of the shuttlesboX,

)and as the filling end s :withdrawn during the v'replenishing operation, the terminal. end

portion ofthefilling'thread is' liable 1tobe pinched between the shuttle andthe wall of ltheshuttle-bov unless means isy provided to Ydirect Vthe trailing end into the longitudinal Y -j The front wall of the vshuttle-box is progroove 12 of the shuttle. r f

vided with afseriesof tufts 14; which may be formedof suitable Africtional material .for

l iholding the' Vfilling thread.l In the present instancey Vthese tufts are `formed of bristlesV groove 12. ofthe shuttle 'when the Vlatter is in the replenishing box." The effectof. this is that the tufts 14 serve to hold the filling t thread or trailing end in the groovelQof the shuttle, and as the Vtrailing end ispfwithdrawn, these tufts, and more particularly .theone at the entrance' portion, of the shuttle-box, will direct the trailing end upwardly into the groove so that it may be readily withdrawn from the shuttle eye and follow the ejected filling carrier.

. In'fpracticeit is found desirable. to Vprovide-'a seriesfof'the tuftsor bristles to effectively hold and position the trailing end lofffilling l.in the groove of they shuttle. AIn

.- Ythe present instance three lof these'are .indicated, one near the entrance of the shuttlebofX,fone near the closedv or outer end of the lshuttle-box adjacent the delivery eye of fthe shuttle, and' another intermediate the two, the construction .being such that as the inthe longitudinal groove of the shuttle by the series ,tuftsY orbristles secured to the front wall of the shuttle-bogg.v ""1 :In the present `instance;"the tufts or `bristles,ltare inclosed in a tube 15 which is passed through the lug 16 and the front wall ofy the shuttle-box. A set screw A174 .SQTVes to hold the tube 15 in adjustedl position, wherebyfthe/tufts.or bristles may be adjusted more orless linwardly relative to the shuttle-box in order to properly adapt them fto'performtheirintended purpose. Byprovidingv4 a number ofy fixed tufts or bristles on ,the front wallof the shuttle-box in line 'with the longitudinal .groove 125` of: the shuttle, the trailing end of the filling may not only Ebepositionedin-the longitudinal --groove of the shuttle Vwhen the; shuttle is boXed,e-butbe maintained insuchl groove to facilitatel its vreadyremoval from between the shuttle and adjacent-wallofftheshuttle box as the filling carrier or bobbin is ejected from-the shuttle. n f A -g-,Any usual or well-known form offilling parting means may be employed, but in the present instance ofthe invention the shuttle feeler 18 carries the parting means 19, both ofA Tsaidfmembers being moved rearwardly into'operative position, as' usual ,ill this type of looms when callfor filling replenishment l isY made; -If 'desi1e'd,fthe` shuttle feeler- 18 Ymay 'be provided with f clamping means to :clamp the`- filling thread a leading from the cloth selva'ge,` as vindicatedin Fig. 1, and carry such end of filling into position to be parted by the *temple-thread cutter 20,
